The article touches on that. The 90% number has an accompanying chart with seizures by year in pounds from both ports of entry and also between the ports, citing U.S. Customs and Border Protection drug seizure statistics. So, that's 90% of total fentanyl seized, not 90% of total fentanyl attempted.

The article later cites a Homeland Security testimony to the U.S. House of Representatives that states only an estimated 25% of attempted fentanyl is seized.

Seems to happen somewhat regularly:

Someone feel free to double check those are all separate recalls, but I think they are. How often does this happen with other makes?

Self upvotes feel fine yet self boosts feel excessive to me, but I don't have an actual reason for thinking that.
